Two Rulebooks for One Battery: The EU's Recycled-Content Floors and China's Digital ID

In one line: The EU regulates batteries by asking "how much recycled material is in it"; China regulates them by asking "whose battery is this, and where did it go". Both regimes tighten around 2027.

1. Two timelines, tightening almost in step

2. The EU's lever: make recycled content verifiable — and compulsory

2.1 Recycled-content floors: two phases, four metals

(Legal basis: Regulation (EU) 2023/1542, Articles 8(2) and 8(3))

These are hard floors, not aspirational targets — miss them and the battery cannot enter the EU market.

2.2 The battery passport: turning a battery into a queryable record

The digital battery passport becomes mandatory on 18 February 2027. Its content specification (Annex XIII) covers four core elements: unique identifier, carbon footprint, recycled content, and due diligence.

In other words, the passport is the carrier for the first three requirements. Without it, content and footprint cannot be verified.

2.3 Carbon footprint: three stages — with one critical precondition

⚠️ A detail that must be pointed out: as of 26 September 2026, the delegated acts setting out the calculation and verification methods had not yet been adopted — and all three stages hang on "N months after the act enters into force". This means the actual application dates may slip. When reading this regulation, look at the status of the delegated acts, not just the dates.

2.4 The recycling end: efficiency and material-recovery targets

• Recycling efficiency floors: lead-acid 75% → 80% (2030); lithium-based 65% → 70% (2030)
• Material recovery rates: by end-2027 — cobalt/copper/lead/nickel 90%, lithium 50%; by end-2031 — 95% / 80%
• Collection rates: portable waste batteries 63% (end-2027) → 73% (end-2030); LMT batteries 51% (end-2028) → 61% (end-2031)

Separately, the Critical Raw Materials Act (Regulation (EU) 2024/1252) sets a target of 25% of strategic raw materials from recycling by 2030 — meaning recycling is no longer an environmental topic but a supply-security one.

3. China's lever: make the battery's journey traceable

3.1 The backbone: six-department Order No. 73

The Interim Measures for the Administration of Recycling and Comprehensive Utilisation of Waste Power Batteries from New Energy Vehicles (Joint Order No. 73, published 2025-12-31) is the current core regulation.

Two accompanying mechanisms deserve separate attention:

• A national power-battery traceability information platform
• A power-battery digital ID system

3.2 "Vehicle-and-battery scrapped together"

End-of-life NEVs must be scrapped together with their power battery — a rule that directly closes the loophole of stripping the battery and selling it privately.

3.3 Carbon footprint: China built its own accounting system too

3.4 The recycling end: black-mass import rules

In June 2025, six departments issued import specifications for lithium-ion battery recycled black mass (Source: Ministry of Ecology and Environment press conference, 2026-01-16) — bringing recycled black mass formally into import/export management.

3.5 China's industrial scale (all official figures)

4. Where they actually differ: input end vs circulation end

Put the two regimes side by side and the logic diverges clearly:

The key judgement: these are not substitutes but complementary ends of one chain — the EU pushes the recycling industry from "how much recyclate is used", China pushes formal recycling channels from "where batteries flow". A company serving both export and domestic markets is effectively required to satisfy both directions at once.

5. What it means for industry

1. The EU gate has widened from "product performance" to "material provenance". The content floors from 2031 test not just cell makers but the entire supply chain's ability to source recyclate.

2. China's gate has shifted from "can you collect" to "can you prove". The digital ID and traceability platform mean: without verifiable flow data, scale alone does not constitute compliance.

3. Both regimes are turning "data capability" into hard currency. The EU wants a passport (footprint, recycled content, due diligence); China wants you on a platform (coding, flow, reporting) — both demand the same thing: structured, verifiable, traceable data.

4. For recycled-material suppliers (including rCB and other recyclates), this is a structural demand-side tailwind. Content floors create mandatory demand; traceability regimes create an advantage for formal channels. But only if you can produce the data both sides will accept.

【inference】Whether the two regimes will ever recognise each other (e.g. whether Chinese carbon-footprint accounting can be used for EU reporting) has no published timetable or mutual-recognition arrangement. Companies should assume "no mutual recognition" when building their data systems.
